I wrote an internal plug-in for Imlib2. I also lost one afternoon on ImageMagick yesterday; its rendering scheme is to X-unfriendly: although there is internal support for conversion to X images and rendering them, nothing of this is available at the user level. One may render in a pixel-by-pixel manner, but this is way too slow. Unfortunately, Imlib2 has no support for animated gifs. > A propos, you may also want to look at > > * http://www.antigrain.com/ (more exotic) > * http://www.cairographics.org/ Henri told me about Cairo. Antigrain looks nice too. At a certain point, it would be good to replace all rendering inside TeXmacs by a library like this one. This should be fairly easy, because we already have an abstract "ps_device" and we always use shadows before rendering. It would suffice to replace the shadow by a buffer from another library and write fast routines for displaying them to X Drawables (if not already supported by the library).
